Article Title: Sex-specific dysregulation of cysteine oxidation and the methionine and folate cycles in female cystathionine gamma-lyase null mice: a serendipitous model of the methylfolate trap
doi: 10.1242/bio.013433
Figure Lengend Snippet: Methionine, folate and cysteine metabolism in mammals. (A) The transsulfuration and cysteine oxidation pathways and, methionine and folate cycles are shown. Betaine-homocysteine S-methyltransferase (BHMT), cystathionine β-synthase (CBS), cystathionine γ-lyase (CGL), cysteine dioxygenase (CDO), cysteinesulfinate decarboxylase (CSAD), glutamic-oxaloacetic transaminase (GOT), glycine N-methyltransferase (GNMT), methionine adenosyl transferase (MAT1A), methionine synthase (MTR), methylenetetrahydrofolate reductase (MTHFR), S-adenosyl homocysteine hydrolase (SAHH). (B) Cgl null female but not male mice exhibit severely elevated levels of plasma tHcy. Plasma levels of tHcy in wild type (WT) mice plus and minus treatment with the CGL specific inhibitor PPG and untreated male and female Cgl null mice. Values shown represent the mean±s.d., n =6, *** P <0.001.
